FIELD OF THE DISCLOSURE

This disclosure relates generally to media monitoring and, more particularly, to using messaging associated with adaptive bitrate streaming to perform media monitoring for mobile platforms.

BACKGROUND

The use of mobile platforms, such as smartphones, tablet computers, notebook computers, etc., to present media, such as media content, media advertisements, etc., has become commonplace. Accordingly, enhancing audience measurement campaigns to include monitoring of media impressions, such as impressions related to presentations of media content, media advertisements, etc., on mobile platforms can be valuable to content providers, advertisers, etc. To increase the value of the audience ratings data obtained from such audience measurement campaigns, audience measurement entities endeavor to augment media impression data with demographic information concerning the audience of the media impressions. Prior audience measurement techniques typically rely on monitoring statistically selected panels of audience members to obtain the demographic information for inclusion in the audience ratings data.

DETAILED DESCRIPTION

Methods, apparatus, systems, storage media, etc., to perform media monitoring for mobile platforms using messaging associated with adaptive bitrate streaming are disclosed herein. Example methods disclosed herein to monitor media on a mobile platform include accessing a first uniform resource locator (URL) included in a first message originated by the mobile platform to stream first media according to an adaptive bitrate streaming protocol. Such disclosed example methods also include requesting network log information corresponding to the first URL from a service provider providing network access for the mobile platform. Such disclosed example methods further include monitoring presentation of the first media on the mobile platform using the network log information.

In some such disclosed example methods, the network log information includes (1) a timestamp corresponding to when the first message including the first URL was logged by the network, and/or (2) location information specifying a location of the mobile platform at a time when the first message including the first URL was logged by the network. Additionally or alternatively, some such disclosed example methods further include obtaining demographic information, in addition to the network log information, in response to providing the first URL to the service provider. In some such examples, the network log information and the demographic information omit personal information related to a subscriber associated with the mobile platform.

Additionally or alternatively, in some such disclosed example methods, the requesting of the network log information includes sending a request including the first URL and a time range associated with when the first URL was detected to the service provider.

Additionally or alternatively, in some such disclosed example methods, monitoring the presentation of the first media on the mobile platform includes combining the network log information with media identification information associated with the first URL

Additionally or alternatively, some such disclosed example methods further include requesting, from the service provider, network log information corresponding to other URLs included in subsequent messages originated by the mobile platform to stream the first media according to the adaptive bitrate streaming protocol. Some such example methods also include determining ratings data associated with the presentation of the first media on the mobile platform using the network log information corresponding to the first URL and the network log information corresponding to the other URLs, with the ratings data having a time granularity corresponding to time intervals between media segments of the first media identified by the first message and the subsequent messages.

Additionally or alternatively, some such example methods disclosed herein further include detecting the first message using at least one of an application executing on the mobile platform or a proxy server in communication with the mobile platform. In some such examples, detecting the first message includes accessing the first message, and processing the first URL in the first message to detect information indicating that the first URL conforms to the adaptive bitrate streaming protocol. In some examples disclosed herein, the adaptive bitrate streaming protocol corresponds to at least one of hypertext transfer protocol (HTTP) live streaming (HLS), dynamic adaptive streaming over HTTP (DASH), smooth streaming, etc.

Some example methods disclosed herein to monitor media on a mobile platform include accessing a request received from an audience measurement entity (AME) for network log information corresponding to a first URL. In such examples, the first URL is associated with a first message originated by the mobile platform to stream first media according to an adaptive bitrate streaming protocol. The adaptive bitrate streaming protocol may correspond to, for example, HLS, DASH, smooth streaming, etc. Some such disclosed example methods also include retrieving the network log information corresponding to the first URL, and returning the network log information to the AME in response to the request.

In some such disclosed example methods, the network log information includes (1) a timestamp corresponding to when the first message including the first URL was logged by the network, and/or (2) location information specifying a location of the mobile platform at a time when the first message including the first URL was logged by the network. Additionally or alternatively, some such disclosed example methods further include omitting personal information related to a subscriber associated with the mobile platform from the network log information before returning the network log information to the AME.

Additionally or alternatively, in some such disclosed example methods, the request received from the AME includes the first URL and a time range associated with when the first URL was detected by the AME. In some such disclosed example methods, retrieving the network log information includes querying network log storage using the first URL and the time range. Some such disclosed example methods also include receiving, in response to the query, a timestamp corresponding to when the first message including the first URL was logged by the network. Some such disclosed example methods further include receiving, in response to the query, location information specifying a location of the mobile platform at a time when the first message including the first URL was logged by the network.

Additionally or alternatively, some such disclosed example methods further include querying a database to obtain demographic information, in addition to the network log information, corresponding to the first URL, and returning the demographic information, in addition to the network log information, to the AME in response to the request. Some such disclosed example methods further include omitting personal information related to a subscriber associated with the mobile platform from the demographic information before returning the demographic information to the AME.

These and other example methods, apparatus, systems, storage media, etc., to perform media monitoring for mobile platforms using messaging associated with adaptive bitrate streaming are disclosed in further detail below.

As mentioned above, prior audience measurement techniques typically rely on monitoring statistically selected panels of audience members to obtain demographic information to be included in and/or used to otherwise augment audience ratings data. However, such panel-based audience measurement techniques may be unable to perform accurate media monitoring for mobile platforms. For example, given the number and variety of media sources accessible via modern mobile platforms, the size of a statistically selected panel may be too small to capture the large number of different media impressions attributable to a population of mobile platform users in a statistically meaningful manner. For example, many online streaming services provide access to thousands, or even millions, of different media programs capable of being viewed on-demand at any time. A typical audience measurement panel may contain only hundreds or a few thousand panelists and, thus, may be unable to accurately reflect the different media impressions occurring in a large population of mobile users able to access such a plethora of different media choices.

Example mobile platform media monitoring solutions disclosed herein, which use messaging associated with adaptive bitrate streaming to perform media monitoring for mobile platforms, are able to solve technical problems associated with obtaining accurate demographic data for use in monitoring media impressions on mobile platforms. For example, some example mobile platform media monitoring solutions disclosed herein solve such problems by using URLs associated with media being streamed to mobile platforms to obtain detailed demographic information from the wireless service providers providing network access to the mobile platforms. Wireless service providers typically maintain databases containing subscriber data providing demographic information concerning their subscribers. Additionally, wireless service providers typically collect network logs documenting the network traffic associated with mobile platforms communicating with their respective networks. Such network logs can contain demographic-related information, such as the locations of the mobile platforms in the network when particular traffic occurred, as well as the specific times when such traffic occurred in the network. Also, the timing data obtainable from the network logs may be more accurate, or have finer granularity, than the timing data that a prior audience measurement system may otherwise be able to determine for monitored media impressions. As disclosed in further detail below, example mobile platform media monitoring solutions disclosed herein enable an audience measurement entity to receive, from a wireless provider, provider data including such demographic information (e.g., location information, subscriber information, etc.) and time information, which can be associated with media impressions monitored on one or more mobile platforms.

Turning to the figures, a block diagram of an example environment of use 100 including an example audience measurement system 102 to perform media monitoring for mobile platforms using messaging associated with adaptive bitrate streaming, as disclosed herein, is illustrated in FIG. 1. The example environment of use 100 of FIG. 1 includes one or more mobile platforms, such as an example mobile platform 105, operating in an example access network 110 implemented by a service provider. In the example environment of use 100 of FIG. 1, the access network 110 provides the mobile platform 105 with access to the Internet 115 and/or any other network, such as a content delivery network (CDN), a proprietary network, etc. Via the example access network 110 and the Internet 115, the mobile platform 105 of the illustrated example is able to access one or more data sources, including one or more media streaming servers, such as an example streaming media server 120. For example, the mobile platform 105 is able to access the streaming media server 120 and/or other servers (e.g., an ad server, etc.) via the access network 110 and the Internet 115, and receive and present media, including media content, such as movies, television program, etc., and/or media advertisements, etc., streamed from the streaming media server 120 and/or the other servers.

The example mobile platform 105 of FIG. 1 can correspond to any mobile device, apparatus, system, etc., such as a mobile phone or smartphone, a tablet computer (e.g., an Apple iPad™), a notebook computer, a gaming device (e.g., a Nintendo 3DS™), a personal digital assistant (PDA), etc. The example access network 110 of FIG. 1 can correspond to any type(s), number and/or combination of access networks, such as a mobile cellular network, a wireless local area network (WLAN), such as a WiFi network, a proprietary wireless network, etc. The example streaming media server 120 of FIG. 1 can correspond to a streaming media service, such as Netflix, Hulu, Amazon, etc., accessible from the mobile platform 105. As such, the streaming media server 120 can be implemented by any type(s), number and/or combination of physical and/or virtual servers and/or platforms, such as the example processing platform 1200 of FIG. 12, capable of streaming media over a network to a media device, such as the mobile platform 105.

The example audience measurement system 102 included in the example environment of use 100 of FIG. 1 includes an example meter 125 and an example AME server 130 that use messaging associated with adaptive bitrate streaming to performing media monitoring for mobile platforms, as disclosed herein. In the illustrated example of FIG. 1, the AME server 130 can be implemented by any type(s), number(s) and/or combination of physical and/or virtual servers and/or platforms, such as the example processing platform 1200 of FIG. 12. In the illustrated example of FIG. 1, the meter 125 can be implemented by any type(s), number(s) and/or combination of application(s) (e.g., apps) executing on the mobile platform 105, and/or monitoring devices electrically coupled to (e.g., via an electrical data port), optically couple to (e.g., via an electrical optical port) and/or otherwise in communication with the mobile platform 105, capable of detecting messages originated by the mobile platform 105 to stream media from the streaming media server 120 according to an adaptive bitrate streaming protocol. For example, the meter 125 of the illustrated example detects adaptive bitrate streaming URLs included in messages originated by the mobile platform 105 and to be sent to the streaming media server 120 to request and stream media segments addressed by the adaptive bitrate streaming URLs.

In some examples, the meter 125 is an application that the service provider automatically installs on the mobile platform 105 and/or causes to be automatically downloaded to the mobile platform 105 via the access network 110. In some examples, the streaming media server 120, or another server, causes the meter 125 to be downloaded to the mobile platform 105 as a condition to access streaming media. Such meters may be referred as non-panelist meters to distinguish them from panelist meters, such as on-device meters, that are provided to panelists statistically selected by an AME for inclusion in an audience measurement panel (and which may include more extensive media monitoring functionality than the non-panelist meters). However, in some examples, the meter 125 may correspond to a panelist mater provided by an AME. As such, the mobile platform media monitoring solutions disclosed herein can be used to monitor a mobile platform regardless of whether the mobile platform is associated with an AME panelist.

In adaptive bitrate streaming, media to be streamed is encoded into two or more alternative media streams having different data rates (and, thus, different quality). Each alternative media stream is then segmented into short segments, such as 10 second segments or segments having some other duration. To receive streaming media from the streaming media server 120 according to an adaptive bitrate streaming protocol, the mobile platform 105 requests successive media segments (e.g., successive 10 sec. segments) using the adaptive bitrate streaming URLs identifying the segments. Each time a next segment is to be requested, the mobile platform 105 can select among the different next segments corresponding to the different alternative streams, thereby permitting the mobile platform 105 to adapt media quality to the available data rate. In the illustrated example of FIG. 1, the meter 125 detects the adaptive bitrate streaming URLs accessed by the mobile platform 105, and provides the detected adaptive bitrate streaming URLs to the AME server 130 for further processing.

For example, the AME server 130 of the illustrated example receives the adaptive bitrate streaming URLs and identifies the media being streamed to and presented by the mobile platform 105 at a resolution corresponding to the segment duration (e.g., such as a 10 second resolution). In some examples, the AME server 130 maintains a database and/or other storage mechanism capable of linking resource identifier information (e.g., domain name and path information) in URLs to different source media. For example, the AME server 130 may determine the resource identifier information for different source media accessible from the streaming media server 120 (and other streaming media servers) via information reported and updated by the operator(s) of the streaming media server 120 (and other streaming media servers), such as Netflix, Hulu, Amazon, etc. Additionally or alternatively, the AME server 130 may determine the particular source media linked to resource identifier information included in the adaptive bitrate streaming URLs reported by meters, such as the meter 125, by accessing the source media addressed by a particular resource identifier and identifying the media using any appropriate media identification technique(s) (e.g., watermark/code matching, signature matching, etc.).

For example, the AME server 130 can use one or more media identification technique(s) employing watermarks and/or signatures to identify media accessed using a resource identifier included in a URL. In the context of media monitoring, watermarks may be transmitted within and/or with media signals. For example, watermarks can be used to transmit data (e.g., such as identification codes, ancillary codes, etc.) with media (e.g., inserted into the audio, video, or metadata stream of media) to uniquely identify broadcasters and/or media (e.g., content or advertisements), and/or to convey other information. Watermarks are typically extracted using a decoding operation.

In contrast, signatures are a representation of some characteristic of the media signal (e.g., a characteristic of the frequency spectrum of the signal). Signatures can be thought of as fingerprints. Signatures are typically not dependent upon insertion of identification codes (e.g., watermarks) in the media, but instead preferably reflect an inherent characteristic of the media and/or the signal transporting the media. Systems to utilize codes (e.g., watermarks) and/or signatures for media monitoring are long known. See, for example, Thomas, U.S. Pat. No. 5,481,294, which is hereby incorporated by reference in its entirety.

Returning to the example environment of use 100 of FIG. 1, the AME server 130 provides the adaptive bitrate streaming URLs detected for one or more mobile platforms, such as the mobile platform 105, as well as any timing data associated therewith, to the service provider operating the access network 110 to request provider information, such as network log information, subscriber information, etc., to be used to augment the audience ratings data determined by the AME. In the illustrated example, the AME server 130 provides (e.g., in real-time, at reporting intervals, etc.) the adaptive bitrate streaming URLs detected for one or more mobile platforms, such as the mobile platform 105, to an example operations support system (OSS) 135 used by the service provider to manage the example access network 110. In the illustrated example of FIG. 1, the OSS 135 includes an example network log server 140 to store network logs documenting the network traffic associated with mobile platforms, such as the mobile platform 105, operating in and/or communicating with the provider's access network 110. The example OSS 135 of FIG. 1 also includes an example subscriber database server 145 to store subscriber data, which includes demographic information concerning the provider's subscribers. The network log server 140 and/or the subscriber database server 145 can be implemented by any type(s), number(s) and/or combination of physical and/or virtual servers and/or platforms, such as the example processing platform 1200 of FIG. 12.

In some examples, in response to receiving the adaptive bitrate streaming URLs in a request for provider information, the OSS 135 compares the adaptive bitrate streaming URLs to the network logs stored in the network log server 140 to, for example, identify the mobile platform(s), such as the mobile platform 105, that accessed the adaptive bitrate streaming URLs, identify the times at which the adaptive bitrate streaming URLs were accessed/logged, determine location information for the mobile platform, such as the mobile platform 105, at the times the adaptive bitrate streaming URLs were accessed/logged, etc. In some examples, the OSS 135 uses the mobile platform identification information obtained from the network logs to further retrieve subscriber data associated with the identified mobile platform(s), such as the mobile platform 105, from the subscriber database server 145. Such subscriber data can include, for example, any demographic-related data, such as an address of the subscriber, an age of the subscriber, a gender of the subscriber, an ethnicity of the subscriber, an income of the subscriber, an education level of the subscriber, a service tier subscribed to by the subscriber, etc., and/or any other subscriber data stored in the subscriber database server 145. Because the adaptive bitrate streaming URLs included in request(s) from the AME server 130 may be associated with any customers/subscribers, and not just panelists of the AME, the OSS 135 can retrieve network log information and/or subscriber data associated with any customers/subscribers, and not just panelists of the AME.

In some examples, the AME server 130 includes a time range or ranges corresponding to when the adaptive bitrate streaming URLs were detected/logged by the meter 125 in the request(s) for provider information sent to the OSS 135. In such examples, the time range(s) can assist the OSS 135 in narrowing the search of the network logs stored by the network log server 140 and/or the search of the subscriber data stored in the subscriber database server 145 when determining the provider information to be reported in response to the request. For example, if the request for provider information includes adaptive bitrate streaming URLs for multiple different mobile platforms and/or corresponds to a substantially long time interval (e.g., tens of minutes, hours, etc.), timing data provided by the AME server 130 in the request may assist the OSS 135 to narrow its searches to the relevant times/time ranges. In some examples, the timing data available to the AME server 130 is less accurate than the timing data maintained by the network log server 140 or, more generally, the OSS 135 and, as such, the AME server 130 is able to use the timing data (e.g., timestamps) retrieved from the network log server 140 to improve monitoring accuracy.

In some examples, the OSS 135 processes the retrieved network log information and/or subscriber data corresponding to the adaptive bitrate streaming URLs to determine provider information including the network log information and/or subscriber data. In some examples, such data is aggregated or otherwise made anonymous to protect the privacy of the service provider's subscribers (e.g., and, thus, the users of the mobile platform, such as the mobile platform 105, operating in and/or communicating with the access network 110.). For example, the resulting network log information returned by the OSS 135 to the AME server 130 for the adaptive bitrate streaming URLs included in the request can include, but is not limited to, timestamps indicating the times at which the adaptive bitrate streaming URL(s) were accessed/logged, location data (e.g., such as location information generalized to a cell identifier level, ZIP+4 data level, etc.) indicating the location(s) of the mobile platform(s), such as the mobile platform 105, when the adaptive bitrate streaming URL(s) was(were) accessed/logged, etc., but which omits any personal identification information. Similarly, the resulting subscriber data returned by the OSS 135 to the AME server 130 for the adaptive bitrate streaming URLs included in the request can include, but is not limited to, demographic data, such as age, ethnicity, income, education, etc., but which omits any personal identification information.

In the example environment of use 100 of FIG. 1, the AME server 130 receives the service provider information (e.g., network log information, subscriber data, etc.) determined to correspond to the adaptive bitrate streaming URLs provided in the prior request(s) sent by the AME server 130 to the OSS 135. In some examples, the AME server 130 combines media identification information identifying the media accessed using the adaptive bitrate streaming URLs with the service provider information (e.g., timestamps, location information and/or other demographic data, etc.) returned by the OSS 135 to determine audience ratings data for monitoring media impressions on the mobile platform. As noted above, the AME server 130 can determine the particular media accessed by the adaptive bitrate streaming URLs using a previously determined mapping of URL resource identifier information to particular media sources, by detecting identification information embedded in or otherwise accompanying the streamed media, etc. By combining the media identification information available to the AME server 130 with the provider information provided by the service provider (e.g., via the OSS 135), the resulting ratings data determined by the AME server 130 is not only able to identify the media corresponding to media impressions monitored on the mobile platform 105, but is also able to indicate, for example, the time and location of the mobile platform 105 when the media impression occurred, as well as other demographic information characterizing the user exposed to the media impression.

An example procedure to perform media monitoring for mobile platforms using messaging associated with adaptive bitrate streaming in the example environment of use 100 of FIG. 1 is illustrated in FIGS. 2A-C. The example procedure begins in FIG. 2A with the example mobile platform 105 originating example messages 205 including adaptive bitrate streaming URLs, which are sent to the example streaming media server 120 to request delivery of streaming media. In response, the streaming media server 120 streams successive example segments 210 of the requested media to the mobile platform 105. As mentioned above, in adaptive bitrate streaming, media to be streamed is segmented into segments of a specified duration, such as 10 seconds or some other duration. Accordingly, the sequence of adaptive bitrate streaming URLs identify the sequence of segments forming the media stream at a resolution (e.g., 10 second) corresponding to the duration of the segments. In the illustrated example of FIGS. 2A-C, the example OSS 135 also logs contents of the messages 205 (represented in FIG. 2A by the directed line 215), such as the adaptive bitrate streaming URLs, and other network information, such as timestamps indicating when the respective messages 205 were logged, location(s) of the mobile platform 105 at the times when the messages 205 were logged, etc.

In some examples, the messages 205 correspond to a sequence of hypertext transfer protocol (HTTP) GET request messages including respective adaptive bitrate streaming URLs identifying successive message segments forming the media stream to be delivered to the mobile platform 105. Two example sequences of adaptive bitrate streaming URLs that may be included in respective sequences of the messages 205 to request different streaming media are shown in Tables 1 and 2.

With reference to FIG. 2B, the example meter 125 detects the messages 205 originated by the mobile platform 105 and containing the adaptive bitrate streaming URLs. The meter 125 logs the adaptive bitrate streaming URLs included in the detected messages 205, and reports the adaptive bitrate streaming URLs (e.g., in real-time, at reporting intervals, etc.) to the example AME server 130, as represented by the directed line 220 in FIG. 2B. In some examples, the meter 125 also includes a time or a time range associated with a respective individual adaptive bitrate streaming URL or a respective group of adaptive bitrate streaming URLs to indicate, for example, a window of time during which the adaptive bitrate streaming URL(s) was(were) collected by the meter 125.

In some examples, the meter 125 is configured to detect the messages 205 by (1) filtering or otherwise detecting HTTP GET request messages and/or other messages capable of carrying adaptive bitrate streaming URLs, and (2) detecting the adaptive bitrate streaming URLs included in the filtered messages. In some examples, the meter 125 is configured to detect the adaptive bitrate streaming URLs by parsing or otherwise searching the contents of detected HTTP GET request messages for keywords, text strings, etc., indicative of a URL format used by an adaptive bitrate streaming protocol, such as HLS, DASH, smooth streaming, etc. For example, and with reference to Tables 1 and 2, the meter 125 may be configured to search for keywords and/or text strings, such as “segmentN.ts” (where “N” is an integer), “.ts.prdy,” etc., in the URLs included in the detected HTTP GET request messages to determine that the URLs correspond to adaptive bitrate streaming URLs. Additionally or alternatively, the meter 125 may be configured to detect adaptive bitrate streaming URLs by searching for patterns of URLs in successive detected messages that are indicative of patterns associated with adaptive bitrate streaming. For example, the meter 125 may determine that a sequence of URLs included in a corresponding sequence of detected messages correspond to adaptive bitrate streaming URLs if the URLs point to a common domain name, share similar path data, and are spaced apart in time by a duration consistent with an adaptive bitrate streaming protocol.

With reference to FIG. 2C, the example AME server 130 sends requests 225 to the example OSS 135 to request provider information, such as network log information, subscriber demographic data, etc., corresponding to adaptive bitrate streaming URLs included in the requests 225. The adaptive bitrate streaming URLs included in the requests 225 may correspond to a sequence of URLs collected for one mobile platform, such as the mobile platform 105, or sequences of URLs collected for a group of mobile platforms. The OSS 135 uses the adaptive bitrate streaming URLs included in the requests 225, as well as any timing data provided by the AME server 130, to query the network log server 140 for network log information, such as timestamps (which may be more accurate than any timing data provided by the AME server in the requests 225), location information, etc., corresponding to the adaptive bitrate streaming URLs. In some examples, the OSS 135 also uses the adaptive bitrate streaming URLs included in the requests 225, and/or the network log information retrieved from the network log server 140 in response to the queries, to query the subscriber database server 145 for subscriber demographic data corresponding to the adaptive bitrate streaming URLs. The OSS 135 then sends responses 230 to the AME server 130 containing the provider data, such as the retrieved network log information (e.g., timestamps, location data, etc.) and/or the subscriber demographic data, corresponding to the adaptive bitrate streaming URLs included in the requests 225. In some examples, the OSS 135 processes the network log information retrieved from the network log server 140 and/or the subscriber demographic data retrieved from the subscriber database server 145 to omit personal identification data before including the network log information and/or the subscriber demographic data in the responses 230 to be sent to the AME server 130. The AME server 130 then uses the provider information included in the responses 230 to monitor media impressions on the mobile platform 105 and to determine associated audience rating data.

A block diagram of a second example environment of use 300 including a second example audience measurement system 302 to perform media monitoring for mobile platforms using messaging associated with adaptive bitrate streaming as disclosed herein is illustrated in FIG. 3. The second example environment of use 300 includes many elements in common with the environment of use 100 of FIGS. 1 and 2A-C. As such, like elements in FIGS. 1 and 3 are labeled with the same reference numerals. The detailed descriptions of these like elements are provided above in connection with the discussions of FIGS. 1 and 2A-C and, in the interest of brevity, are not repeated in the discussion of FIG. 3.

Turning to FIG. 3, the example environment of use 300 includes the example mobile platform 105, the example access network 110, the Internet 115, the example media streaming server 120, the example OSS 135, the example network log server 140 and the example subscriber database server 145 of FIG. 1. The example audience measurement system 302 included in the example environment of use 300 of FIG. 3 also includes the example AME server 130 of FIG. 1. Descriptions of these elements are provided above in connection with the descriptions of FIGS. 1 and 2A-C. However, instead of including the meter 125 to monitor the mobile platform 105, the example audience measurement system 302 included in the example environment of use 300 of FIG. 3 includes an example proxy server 325 to detect the messages 205 originated by the mobile platform 105 and including adaptive bitrate streaming URLs to be used for media monitoring. In the illustrated example of FIG. 3, the mobile platform 105 is configured to access the Internet 115 (or other network) via the proxy server 325. Some example techniques for configuring the mobile platform 105 to access the Internet 115 (or other network) via the proxy server 325 are described in U.S. Patent Publication No. 2012/0042005, U.S. Patent Publication No. 2012/0042367 and U.S. Pat. No. 8,594,617, which are incorporated herein by reference in their respective entireties. The proxy server 325 detects the messages 205 from the mobile platform 105 and/or other mobile platforms configured to access the Internet 115 (or other network) via the proxy server 325, logs the detected messages 205, and reports the adaptive bitrate streaming URLs (e.g., in real-time, at reporting intervals, etc.) to the example AME server 130. In some examples, the proxy server 325 also includes a time or a time range associated with an individual adaptive bitrate streaming URL or a group of adaptive bitrate streaming URLs to indicate, for example, a window of time during which the adaptive bitrate streaming URL(s) was(were) collected by the proxy server 325.

In some examples, the proxy server 325 is configured to detect the messages 205 by (1) filtering or otherwise detecting HTTP GET request messages and/or other messages capable of carrying adaptive bitrate streaming URLs, and (2) detecting the adaptive bitrate streaming URLs included in the filtered messages. Like the example meter 125, in some examples, the proxy server 325 is configured to detect the adaptive bitrate streaming URLs by parsing or otherwise searching the contents of detected HTTP GET request messages for keywords, text strings, etc., indicative of a URL format used by an adaptive bitrate streaming protocol, such as HLS, DASH, smooth streaming, etc. For example, and with reference to Tables 1 and 2, the proxy server 325 may be configured to search for keywords and/or text strings, such as “segmentN.ts” (where “N” is an integer), “.ts.prdy,” etc., in the URLs included in detected HTTP GET request messages to determine that the URLs correspond to adaptive bitrate streaming URLs. Additionally or alternatively, like the meter 125, the proxy server 325 may be configured to detect adaptive bitrate streaming URLs by searching for patterns of URLs in successive detected messages that are indicative of patterns associated with adaptive bitrate streaming. For example, the proxy server 325 may determine that a sequence of URLs included in a corresponding sequence of detected messages corresponds to adaptive bitrate streaming URLs if the URLs point to a common domain name, share similar path data, and/or are spaced apart in time by a duration consistent with an adaptive bitrate streaming protocol.

Although example mobile platform media monitoring solutions have been disclosed herein in the context of the example environments of use 100 and 300, such solutions are not limited thereto. For example, a system that is to use messaging associated with adaptive bitrate streaming to perform media monitoring for mobile platforms as disclosed herein may include any number(s) and/or type(s) of mobile platforms 105, access networks 110, Internet and/or other networks 115, media streaming servers 120, OSSs 135, network log servers 140 and/or subscriber database servers 145. Additionally or alternatively, a system that is to use messaging associated with adaptive bitrate streaming to perform media monitoring for mobile platforms as disclosed herein may include multiple AME servers 130, such as different servers configured to monitor different access networks 110 and, thus, configured to interface with different OSSs 135. Additionally or alternatively, a system that is to use messaging associated with adaptive bitrate streaming to perform media monitoring for mobile platforms as disclosed herein may include one or more meters 125, one or more proxy servers 325, and/or any combination thereof to collect the adaptive bitrate streaming URLs corresponding to the different media being streamed to different mobile platforms. Also, using messaging associated with adaptive bitrate streaming to perform media monitoring for mobile platforms as disclosed herein is not limited to use with wireless access networks, but can be used with any type of access network for which network log information and/or subscriber demographic data is maintained.

A block diagram of an example implementation of the meter 125 included in the example environment of use 100 of FIGS. 1 and 2A-C is illustrated in FIG. 4. For convenience and without loss of generality, the meter 125 of FIG. 4 is described in the context of being used to monitor the example mobile platform 105 in the example environment of use 100 of FIGS. 1 and 2A-C. The example meter 125 of FIG. 4 includes an example message detector 405 to detect messages that include adaptive bitrate streaming URLs, such as the example messages 205 originated by the mobile platform 105. In some examples, the message detector 405 detects the messages 205 by initially filtering messages originated at the mobile platform 105 (e.g., message prepared and to be sent by the mobile platform 105) to identify those candidate messages likely to include adaptive bitrate streaming URLs, such as HTTP GET messages. For example, the message detector 405 may be configured to monitor a protocol call stack, such as a transmission control protocol/Internet protocol (TCP/IP) protocol stack, implemented on the mobile platform 105, and/or to monitor one or more network interfaces of the mobile platform 105, etc., to capture and filter (e.g., identify) candidate messages, such as HTTP GET messages, being prepared for transmission by the mobile platform 105.

In some examples, the message detector 405 then processes the filtered, candidate messages to detect adaptive bitrates streaming URLs included in the messages. For example, and as described above, the message detector 405 may be configured to detect the adaptive bitrate streaming URLs by parsing or otherwise searching the contents of candidate messages, such as HTTP GET messages originated by the mobile platform 105, for keywords, text strings, etc., indicative of a URL format used by an adaptive bitrate streaming protocol, such as HLS, DASH, smooth streaming, etc. Additionally or alternatively, the message detector 405 may be configured to detect adaptive bitrate streaming URLs by searching for patterns of URLs in successive candidate messages that are indicative of patterns associated with adaptive bitrate streaming. For example, and as described above, the message detector 405 may determine that a sequence of URLs included in a respective sequence of candidate messages, such as HTTP GET messages originated by the mobile platform 105, correspond to adaptive bitrate streaming URLs if the URLs point to a common domain name, share similar path data, and/or are spaced apart in time by a duration consistent with an adaptive bitrate streaming protocol.

The example meter 125 of FIG. 4 also includes an example URL reporter 410 to log the adaptive bitrate streaming URLs detected by the message detector 405. For example, the URL reporter 410 may store the detected adaptive bitrate streaming URLs in volatile and/or non-volatile memory, storage, etc., such as the example volatile memory 1214, the example non-volatile memory 1216, and/or the example mass storage device(s) 1228, etc., included in the example processor platform 1200 of FIG. 12. The URL reporter 410 of the illustrated example also reports the logged adaptive bitrate streaming URLs to, for example, the AME server 130. For example, the URL reporter 410 may report the logged adaptive bitrate streaming URLs in real-time, at reporting intervals, when a storage threshold is met, etc., or via any combination of these techniques. In some examples, the URL reporter 410 also includes times or time ranges associated with respective individual adaptive bitrate streaming URLs or respective groups of adaptive bitrate streaming URLs in the information reported to the AME server 130 to indicate, for example, windows of time during which different adaptive bitrate streaming URLs, or groups of URLs, were collected by the meter 125.

A block diagram of an example implementation of the proxy server 325 included in the example environment of use 300 of FIG. 3 is illustrated in FIG. 5. For convenience and without loss of generality, the proxy server 325 of FIG. 5 is described in the context of being used to collect and report adaptive bitrate streaming URLs included in messages sent by mobile platform(s), such as the example mobile platform 105, in the example environment of use 300 of FIG. 3. The example proxy server 325 of FIG. 5 includes an example message detector 505 to detect messages, such as the example messages 205, originated by mobile platforms, such as the mobile platform 105, and which include adaptive bitrate streaming URLs. In some examples, the message detector 505 detects the messages 205 by initially filtering messages originated by and received from mobile platforms, such as the mobile platform 105, to identify those candidate messages likely to include adaptive bitrate streaming URLs, such as HTTP GET messages.

In some examples, the message detector 505 then processes the filtered, candidate messages to detect adaptive bitrate streaming URLs included in the messages. For example, and as described above, the message detector 505 may be configured to detect the adaptive bitrate streaming URLs by parsing or otherwise searching the contents of candidate messages, such as HTTP GET messages originated by and received from mobile platforms, such as the mobile platform 105, for keywords, text strings, etc., indicative of a URL format used by an adaptive bitrate streaming protocol, such as HLS, DASH, smooth streaming, etc. Additionally or alternatively, the message detector 505 may be configured to detect adaptive bitrate streaming URLs by searching for patterns of URLs in successive candidate messages that are indicative of patterns associated with adaptive bitrate streaming. For example, and as described above, the message detector 505 may determine that a sequence of URLs included in a corresponding sequence of candidate messages, such as HTTP GET messages originated by and received from mobile platforms, such as the mobile platform 105, correspond to adaptive bitrate streaming URLs if the URLs point to a common domain name, share similar path data, and are spaced apart in time by a duration consistent with an adaptive bitrate streaming protocol.

The example proxy server 325 of FIG. 4 also includes an example URL reporter 510 to log the adaptive bitrate streaming URLs detected by the message detector 505. For example, the URL reporter 510 may store the detected adaptive bitrate streaming URLs in volatile and/or non-volatile memory, storage, etc., such as the example volatile memory 1214, the example non-volatile memory 1216, and/or the example mass storage device(s) 1228, etc., included in the example processor platform 1200 of FIG. 12. The URL reporter 510 of the illustrated example also reports the logged adaptive bitrate streaming URLs to, for example, the AME server 130. For example, the URL reporter 510 may report the logged adaptive bitrate streaming URLs in real-time, at reporting intervals, when a storage threshold is met, etc., or any combination thereof. In some examples, the URL reporter 510 also includes times or time ranges associated with respective individual adaptive bitrate streaming URLs or respective groups of adaptive bitrate streaming URLs in the information reported to the AME server 130 to indicate, for example, windows of time during which different adaptive bitrate streaming URLs, or groups of URLs, were collected by the proxy server 325.

A block diagram of an example implementation of the AME server 130 included in the example environments of use 100 and/or 300 of FIGS. 1 and 3, respectively, is illustrated in FIG. 6. The example AME server 130 of FIG. 6 includes an example URL collector 605 to collect (e.g., receive and store) adaptive bitrate streaming URLs reported by meter(s), such as the example meter 125, and/or proxy server(s), such as the example proxy server 325, operating in the example environments of use 100 and/or 300. For example, the URL collector 605 may store the reported adaptive bitrate streaming URLs, along with any times and/or time range reported with the URLs, in volatile and/or non-volatile memory, storage, etc., such as the example volatile memory 1214, the example non-volatile memory 1216, and/or the example mass storage device(s) 1228, etc., included in the example processor platform 1200 of FIG. 12.

The example AME server 130 of FIG. 6 also includes an example provider data requestor 610 to request, from one or more service providers, information, such as network log information, subscriber demographic data, etc., corresponding to the adaptive bitrate streaming URLs collected by the URL collector 605. In some examples, the provider data requestor 610 sends requests, such as the example requests 225, to a service provider's OSS, such as the example OSS 135, which include the adaptive bitrate streaming URLs for which provider information is requested. The adaptive bitrate streaming URLs may correspond to one or more URLs (e.g., such as a sequence of URLs) collected for one mobile platform, such as the mobile platform 105, or for several mobile platforms being monitored by the AME server 130. In some examples, the requests 225 sent by the provider data requestor 610 also include times and/or time range information associated with the adaptive bitrate streaming URLs for which provider information is requested. In response to the requests 225, the provider data requestor 610 receives responses, such as the example responses 230, containing the provider information, such as retrieved network log information (e.g., timestamps, location data, etc.) and/or the subscriber demographic data, corresponding to the adaptive bitrate streaming URLs included in the requests 225. In some examples, the provider information included in the responses 230 received by the provider data requestor 610 omits personal identification information to protect the privacy of the service provider's customers.

The example AME server 130 of FIG. 6 further includes an example media identifier 615 to identify the particular media associated with the adaptive bitrate streaming URLs collected by the URL collector 605. In some examples, and as described above, the media identifier 615 maintains a database and/or other storage mechanism capable of linking resource identifier information (e.g., domain name and path information) in URLs to different source media. For example, the media identifier 615 may determine the resource identifier information for different source media accessible from the streaming media server 120 (and/or other streaming media servers) via information reported and updated by the operator(s) of the streaming media server 120 (and/or other streaming media servers), such as Netflix, Hulu, Amazon, etc. Additionally or alternatively, the AME server 130 may determine the particular source media linked to the adaptive bitrate streaming URLs collected by the URL collector 605 by accessing the source media addressed by a particular resource identifier and identifying the media using any appropriate media identification technique(s), such as one or more watermark-based techniques, signature-based techniques, etc.

The example AME server 130 of FIG. 6 includes an example ratings monitor 620 to combine the provider data obtained by the provider data requestor 610 and the media identification data obtained by the media identifier 615 to determine ratings data characterizing, for example, media impressions on mobile platforms, such as the mobile platform 105. In some examples, the ratings monitor 620 combines the media identification information determined by the media identifier 615 for one or a group of adaptive bitrate streaming URLs collected by the URL collector 605 with provider information (e.g., timestamps, location data, subscriber demographic data, etc.) obtained by the provider data requestor 610 for the same adaptive bitrate streaming URL or group of URLs to monitor media impressions associated with a mobile platform, such as the mobile platform 105. In some examples, the ratings monitor 620 determines ratings data for each collected adaptive bitrate streaming URL and, thus, the ratings data has a temporal resolution corresponding to the media segment duration associated with each URL (e.g., such as 10 seconds or some other duration).

For example, for an adaptive bitrate streaming URL or group of URLs collected by the URL collector 605 for the mobile platform 105, the ratings monitor 620 may identify the media associated with the adaptive bitrate streaming URL(s) using the media identification information obtained by the media identifier 615. In such examples, the ratings monitor 620 may use the timestamps included in the provider information obtained by the provider data requestor 610 to determine a time (or time range) corresponding to when a particular segment of the identified media was provided to and/or presented by the mobile platform 105. Additionally or alternatively, the ratings monitor 620 may use the location data included in the provider information obtained by the provider data requestor 610 to determine a location of the mobile platform 105 at the time when the particular segment of the identified media was provided to and/or presented by the mobile platform 105. Additionally or alternatively, the ratings monitor 620 may use the subscriber demographic data included in the provider information obtained by the provider data requestor 610 to determine demographics of the user exposed to the identified media presented by the mobile platform 105. In some examples, the ratings monitor 620 further combines ratings data determined for individual mobile platforms, such as the mobile platform 105, with other mobile platforms and/or other media presentation devices (e.g., such as televisions, desktop computers, gaming consoles, etc.) to determine overall ratings data for one or more audience measurement campaigns.

A block diagram of an example implementation of the OSS 135 included in the example environments of use 100 and/or 300 of FIGS. 1 and 3, respectively, is illustrated in FIG. 7. The example OSS 135 of FIG. 7 includes the example network server 140 and the example subscriber database server 145 described above in connection with the descriptions of FIGS. 1-3. The example OSS 135 of FIG. 7 also includes an example AME request interface 705 to receives requests, such as the example requests 225, from AME servers, such as the example AME server 130, for provider information (e.g., network log information, subscriber demographic data, etc.) corresponding to adaptive bitrate streaming URLs specified in the requests. As noted above, the adaptive bitrate streaming URLs specified in the requests may be associated with one or several different mobile platforms. The AME request interface 705 also returns responses, such as the example responses 230, containing the requested provider information to the requesting AME server. The AME request interface 705 can be implemented by an appropriate type(s) and/or number(s) of network and/or data interface(s), such as the example interface circuit 1220 of FIG. 12.

The example OSS 135 of FIG. 7 further includes an example server querier 710 to query provider servers, such as the network server 140 and the subscriber database server 145, to retrieve provider information corresponding to the adaptive bitrate streaming URLs included in the requests received via the AME request interface 705. In some examples, the server querier 710 queries the network log server 140 using contents of an adaptive bitrate streaming URL to retrieve network log information stored in the network log server 140 and associated with the provided URL contents. For example, in response to receiving an adaptive bitrate streaming URL in a query from the server querier 710, the network log server 140 may find a stored network log entry containing a matching adaptive bitrate streaming URL. The network log server 140 may then return other network information, such as a timestamp for the matching log entry, a mobile platform identifier identifying the particular mobile platform associated with the matching log entry, mobile platform location data included in the matching log entry, etc., in a response to the query.

In some examples, the server querier 710 additionally or alternatively queries the subscriber database server 145 using contents of an adaptive bitrate streaming URL and/or network log information obtained from the network log server 140 for the adaptive bitrate streaming URL to retrieve subscriber data stored in the subscriber database server 145 and associated with the URL. For example, in response to receiving a query from the server querier 710 including a mobile platform identifier indicated by the network log information as being associated with an adaptive bitrate streaming URL, the subscriber database server 145 may find a subscriber database entry containing a matching mobile platform identifier. The subscriber database server 145 may then return other subscriber demographic data, such as an address of the subscriber, an age of the subscriber, a gender of the subscriber, an ethnicity of the subscriber, an income of the subscriber, an education level of the subscriber, a service tier subscriber to by the subscriber, etc., in a response to the query.

The example OSS 135 of FIG. 7 includes an example provider data reporter 715 to process provider information, such as the network log information and/or subscriber demographic data retrieved by the server querier 710, before returning the provider information to an AME server, such as the AME server 130, in a response to a query received by the AME request interface 705. In some examples, the provider data reporter 715 processes the network log information and/or subscriber demographic data retrieved by the server querier 710 to omit any personal identification information, such as a subscriber's name, a subscriber's address, a subscriber's customer/subscriber identification number, etc., to thereby protect the privacy of the service provider's customers/subscribers. The provider data reporter 715 then includes the processed provider information in one or more responses, such as the responses 230, to be returned to the requesting AME server via the AME request interface 705.

While example manners of implementing the example audience measurement systems 102 and 302 are illustrated in FIGS. 1-7, one or more of the elements, processes and/or devices illustrated in FIGS. 1-7 may be combined, divided, re-arranged, omitted, eliminated and/or implemented in any other way. Further, the example mobile platform 105, the example access network 110, the Internet 115, the example streaming media server 120, the example meter 125, the example AME server 130, the example OSS 135, the example network log server 140, the example subscriber database server 145, the example proxy server 325, the example message detector 405, the example URL reporter 410, the example message detector 505, the example URL reporter 510, the example URL collector 605, the example provider data requestor 610, the example media identifier 615, the example ratings monitor 620, the example AME request interface 705, the example server querier 710, the example provider data reporter 715 and/or, more generally, the example system 102 and/or the example system 302 may be implemented by hardware, software, firmware and/or any combination of hardware, software and/or firmware.

Also, one or more of the machine readable instructions represented by the flowcharts of FIGS. 8-11 may be implemented manually.
